Hi,

The following vulnerability was published for perl.

CVE-2026-57433[0]:
| Storable versions before 3.41 for Perl have a signed integer
| overflow when deserializing a crafted SX_HOOK record.
| retrieve_hook_common reads a signed 32-bit item count from an
| SX_HOOK record and calls av_extend with that count plus one. A count
| of I32_MAX wraps the addition to a negative value.  A crafted blob
| passed to thaw or retrieve triggers the overflow; av_extend receives
| the negative count and dies with a panic, terminating the
| deserialization.


If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.

So merging.

Salvatore: This didn't have a CVE number earlier. Would you like me to
retroactively add one to d/changelog in a future upload?

Hi Niko,

Ups, apologies for that!

It is fine, not strictly needed. I made sure to fix the metadata in
the security-tracker now.
